I have an OpenVPN server running on OpenBSD 3.8 (x86). I've been having
intermitten problems with it and reconnection problems. It's openvpn out of
ports for 3.8.
I have it down to right now, sporadically, the OpenVPN server thinks it is
sending UDP packets (and in the logs makes note that it has) but I cannot see
them leaving the external interface...
What can I do to track down where this is going wrong? Is there some way to
see if OpenBSD is taking this packet and then losing it?
I am just not sure where to look next. I've watched it happen, and the traffic
is very low, the utlization is like so:
load averages: 0.40, 0.54, .60
38 processes: 37 idle, 1 on processor
CPU states: 2.7% user, 0.0% nice, 3.7% system, 1.6% interrupt, 92.0% idle
Memory: Real: 678M/824M act/tot Free: 684M Swap: 0K/3072M used/tot
The strange part is that it works fine for a while, then suddenly starts up
with this behavior... We've had this happen with clients on all different
platforms (windows / mac / linux).
We have an upgrade to OpenBSD 4.0 set for the first few weeks of next year...
I've another 3.8 machine running this fine with no problems whatsoever...
Any pointers would be great and very appreciated. I've tried the OpenVPN
lists, but no help there
